WINDOWED RECEPTACLE.

Specification of Letters Patent.

Patented Dec. *7, 1915.

Application filed April 20, 1914. Serial No. 833,102.

State of New Jersey, have invented certain.

new and useful Improvements in Windowed Receptacles, of which the following is a specification.

This inventionrelates to windowed receptacles and particularly to such receptacles as are molded of paper pulp or the like.

The object of my improvements is .to provide a receptacle of the class specified, simple in construction, pleasing in appearance, and reliable in use.

To these ends my improvements comprise features illustrated in their preferred em bodiment in the accompanying drawing where1n l igure 1 1s a side elevation, with a portion thereof in section, of a receptacle of well known form including my improvements. Fig. 2 is a front elevation of a part of what is shown in Fig. 1. Fig. 3 is a cross section on line 3, 3 of Fig. 2. Fig. 1 is a fragmentary sectional elevation of a part of what is shown in Fig. 1. Fig. 5 is a perspective detail view of my improved win dow. Figs. 1, 2 and 3 are to one scale, Fig. 4 is to a much larger scale, and Fig. 5 is to a scale between those of Figs. 1 and 4.

Receptacles such as bottles, for milk and other liquid commodities, have heretofore been made of paper or paper pulp; but for use as containers of milk, receptacles of opaque material are open to the objection that the contents cannot be inspected and therefore the cream line cannot be seen.

My improvements are particularly directed to obviate these objections and provide a receptacle of opaque material having a window therein through which the contents of the receptacle may be inspected. The broad proposition of an opaque receptacle having a window therein is already known but all such receptacles of which I have knowledge have objectionable features of manufacture or use, or both, and the present improvements are directed to provide a receptacle of the character specified in which the recited objections are obviated or mini- Inized.

Directing attention now to the particular features of my improvements, I form the receptacle, preferably of pulp, by some well known means and thereafter otherwise cut, a window opening 2 there through. In making this opening I preferably form the walls 4, 4 thereof parallel with each other transversely of the wall of the receptacle, for reasons more fully set forth hereinafter. Said window opening is illustrated in the figures of the drawing as located in the upper portion of the receptacle and as conforming somewhat to the general contour thereof at the position in which it is located. It will be obvious that the shape, size and location of said window opening may vary according to the requirements of any particular case. In punching said window opening, I form, preferably coincident with said punching, a groove 5 in said receptacle wall, inside the receptacle, around and acent to the window opening. This groove is for the reception of portion 11 of the transparent window 6, see Fig. 5. Said window is preferably formed of some non-frangible material such as celluloid, but

may be made of tough glass or other material. Said window 6 comprises face member 7, preferably flush with the outside 8 of the receptacle wall 10 and provided with a continuous side flange 9, extending therearound and of a height substantially equal to the thickness of wall 10. All portions punch, or

of said flange 9 are parallel with each other transversely of face 7, and said flange is arranged to fit closely against walls 4, 4 of the receptacle window opening to form a tight joint. Said flange 9 is provided at its inner edge with an outwardly and upwardly turned flange 11 therearound for engagement with groove 5 about the window opening in the receptacle. After said window has been forced into place outwardly from within the receptacle, the joint between flange 11 and groove 5 may be sealed by flowing a transparent cement or varnish into the receptacle, thereby forming a film 12 over the whole of the interior, a generous portion finding lodgment in groove 5 against said flange 11. Or said joint may be sealed by some other convenient means.

It will. be obvious that my improvements are not limited to the employment of only one window in one receptacle, but that a plurality of windows in one receptacle may be used if desired.

I thus provide a cheap, simple and eflicient windowed receptacle or bottle adapted for a variety of uses.

I claim:

1. An opaque receptacle including in combination a window opening through a wall of said receptacle, a transparent window forced into said opening and having its outer surface substantially continuous with the adjacent outer surface of said receptacle, and means integral with the window for restraining said window against outward movement.

2. An opaque receptacle including in combination a window opening through a wall of said receptacle having parallel walls, a transparent window forced into said opening and having its outer surface substantially continuous with the adjacent surface of said receptacle, and means integral with the window for restraining said Window against outward movement.

3. An opaque receptacle including in combination a window opening through a wall of said receptacle having parallel walls, a groove in. the inner surface of said receptacle wall around and adjacent to said Window opening, a transparent window forced into said opening and having its outer surface substantially continuous with the adjacent outer surface of said receptacle, and means integral with the window, engaging said groove, for restraining said window against outward movement.

4-. An opaque receptacle including in combination a window opening through a wall of said receptacle having parallel walls, a groove in the inner surface of said receptacle wall around and adjacent to said window opening, a transparent window forced into said opening and having its outer surface substantially continuous with the adjacent outer surface of said receptacle. means integral with the window, engaging said groove, for restraining said window against: outward movement, and means for sealing said window groove engaging means in said groove.

Signed at New York, in the county of New York and State of Yew York, this 17th day of April, 191l before two subscribing witnesses.
